A. n060 : Number of Auto-Restart Attempts Factory setting: 0
(Num of Restarts)
Range: 0 - 10
When a fault occurs during operation, the drive can be programmed for an auto-restart
operation to automatically reset the fault. Auto-restart operation will use the number of
reset attempts set in this parameter, up to the maximum of 10. When set to " 0 ", no
auto-restarts will be attempted.
• The following faults can be automatically reset:
oC: Overcurrent GF: Ground fault
ou: Overvoltage (OV) Uu1: Undervoltage (Power UV)
• The following conditions WILL NOT initiate auto-restart:
1. oL, EF
, PUF or CPF fault.
2. When OC or UV occurs during deceleration.
3. When n055is programmed to stop during momentary power failure (data =
" 0 "). (See paragraph 5.17, MOMENTARY POWER LOSS RIDE-THRU.)
• The number of restart attempts available will be reset to the n060 setting when:
1. 10 minutes has elapsed without a fault occurring.
2. The RESET key, or external Fault Reset push button, is pressed.
3. Power is removed from the Drive.
B. n061 : Fault Contact Status During Auto-Restart (Restart Sel)
This digit controls how the fault contact responds to a drive fault during the auto-restart
operation.
